"You could start the clip by showing your retainer and telling me how you still have it from when you had braces. Hold it your hand and tell me how you know about my (pathetic) retainer fetish and how they make my cock hard. Tell me you are going to show it off for me - pop it in your mouth and show some close-up shots of it in your mouth, smile and tease me with your mouth. You can call me names, encourage me to beg for your retainer and laugh at me. You can pop it in and out and tell me to worship your retainer. Tell me how you know how much I like it and how I have to profess my love of it. You can tell me to repeat phrases if you want - "I am a slave to your retainers", "I will do whatever you say for your retainers". Show some close-ups, encourage me to continue worshipping your retainers while I jerk off. At the end you can make me cum for your retainers. Again, I love harsh, domination and humiliation so if you are comfortable, go nuts! Nothing here is too specific, feel free to play around with ideas. If you could also wear your glasses for the duration, that would be amazing."
